- Liss Vazquez Rodriguez (Max Planck Society (DE))
In this talk, I will present an overview of recent research at ISOLDE that bridges solid-state physics, quantum technologies, nuclear physics, and fundamental interactions. One of our main research directions focuses on understanding and controlling optically active impurity–vacancy complexes (color centers) in diamond, using radioactive isotopes as probes [1]. This work establishes...
Absolute transition strengths between excited states yield fundamental information on nuclear structure. These observables can be determined from level lifetimes. The recoil distance Doppler-shift (RDDS) technique employing so-called plunger devices provides a valuable method for the determination of lifetimes in the picosecond range and has been in the focus of our Cologne group since many...
The region of the nuclear landscape around the doubly-magic $^{132}$Sn is rich in nuclear structure phenomena. A relevant feature in the region is the presence of long-lived isomeric states, which may undergo both $\beta$ and $\gamma$ decay [1-3]. Spin-gap isomers arising from hindered decay routes to lower-lying levels due to a large change in nuclear spin the need for the emission of...
The magnetoelectric coupling effects and ferromagnetic properties of multiferroic bismuth ferrite (BiFeO₃, BFO) nanoparticles at the microscopic scale remain subjects of ongoing scientific discourse. In this study, two local hyperfine interaction techniques—time differential perturbed angular correlation (TDPAC) spectroscopy and transmission Mössbauer (TMS) spectroscopy—were employed to...
In the framework of the HISTARS (HIE-ISOLDE Timing Array for Reaction Studies) project at ISOLDE/CERN, an array is being developed to measure lifetimes of excited nuclear states populated in reactions at HIE-ISOLDE. For particles detection, plastics or fast inorganic scintillators such as GAGG:Ce and YSO are promising candidates due to their non-hygroscopic nature, high density, high light...
